One question for them. Since NHRA Pro Stock is now forced to run Sunoco race fuel instead of VP race fuel like in the past WHY are the teams complaining of inconsistent fuel blends and tuning issues??????



I didn't get a chance to ask him directly because the seminar was over by the time you posted.

But one of the things I learned today is that SR-18 has a "smaller tuning window" in some applications. So maybe that is why some teams are struggling? If that is even the case either way?
